Method#$1$: Using a weighted moving average of $0\mathrm{.}35[$last day$],0\mathrm{.}30[2$ days ago$]0\mathrm{.}15[3$ days ago$],0\mathrm{.}10[4$ days ago$],0\mathrm{.}10[5$ days ago$],$ calculate the daily forecasts for the last $15$ days. In addition, what is the forecast for the Monday of this week?

Method #$2$: Assume that the forycast for Monday of $4$ weeks ago was $570$ units. Using an Exponential Smootiing with $=0\mathrm{.}25,$ calculate the daily forecasts for the last $15$ days. In addition, what is the forecast for the Monday of this week?

Calculate the Mean Squared Error for each of the above methods based on the daily forecasts for the last $15$ days. Which method is more accurate? Why?
